Evaluating a K-Mart Grow Light for Drosophyllum (Dewy Pine)

A grower found a grow light at K-Mart and asks if it's sufficient for Drosophyllum, currently under a 120W bulb.

Assessment: Inadequate

These incandescent-style grow lights (red/orange spectrum) are only suitable for low-light houseplants as supplemental lighting. As sole source, they cause leggy, spindly growth, run hot, and are energy-inefficient.

Recommended Lighting for Drosophyllum

Drosophyllum needs intense light. Options:

• Large compact fluorescent: 65W actual (300W equivalent)
• Small metal halide (e.g., reptile self-ballasted lights like Wonderlite)
• High-output CFLs (search "large compact fluorescent light bulbs")

Invest in proper high-intensity lighting for this full-sun species.
